How do trees with ball seeds contribute to the ecosystem?

Trees with ball seeds, such as oak trees, contribute to the ecosystem by providing food and shelter for various animals. The seeds are a food source for birds, squirrels, and other wildlife, helping to support their populations. Additionally, the trees themselves provide habitat for animals and help to improve air quality by absorbing carbon dioxide and releasing oxygen through photosynthesis. Overall, trees with ball seeds play a crucial role in maintaining biodiversity and supporting the health of the ecosystem.
